Denon AVR-X6700H 11.2-channel A/V Receiver Review Sound United statement regarding 2020 AVR HDMI 2.1 issues

Sound United statement regarding 2020 AVR HDMI 2.1 issues:

Some new gaming source devices that support 4K/120Hz HDR output may not work fully with Denon (or Marantz) 8K AVRs. You may discover this incompatibility issue due to a HDMI chipset mismatch between the devices. When the affected system is connected to the AVR via 8K HDMI input and set to output at 4K/120Hz, and the AVR's 4K Signal Format option is set to "8K Enhanced," you may not see the system's source video on their display, and may not hear the system's source audio processed through the AVR. This problem is only present when a display that supports 4K/120Hz is used.

We are currently investigating the issue further and will offer a permanent solution at a later date. Meanwhile, we would like to provide a couple workarounds to prevent the issue in its current state:

  • You can connect the system to the display directly via HDMI and use the display's ARC/eARC functionality to feed the native audio back to the AVR using the connected HDMI cable between the AVR and display. This will allow users to decode the native audio format sent from the source. With this method, the display's CEC/ARC option must be enabled as well as the AVR's HDMI Control and/or the AVR's ARC option. In the AVR, this option is located within the GUI under "Video – HDMI Setup."

  • Another workaround is to leave or change the source's video output to 4K/60Hz instead of 4K/120Hz until a permanent solution is available. This will ensure reliable communication between the source, the AVR and the display. The source's default is set to output at 4K/60Hz, so if no change was initiated out of the box, then nothing further needs to be done.

We apologize for this inconvenience and we are currently working tirelessly to release a permanent solution so you can enjoy the 4K/120Hz experience using the latest sources with your AVR. We will have an update soon regarding the timeline of a permanent solution. We appreciate your patience.

For Fire TV Cube 2 and Fire TV Stick Lite the Denon AVR X6700H (2020 model) when you turn it Off and On, the Fire TV Adjusting Video Frame Rate stops working (when Settings>Display & Sounds>Display>Video Resolution> Auto). The Adjusting Video Frame Rate worked perfectly with the X6500H 2018 model. So Denon has more than just the HDMI 2.1 Chip bug in this AVR. Hopefully Denon will fix this soon.

As the owner of a 2018 Denon AVR, I've had real problems getting its ARC function to work with an LG OLED TV. An internet search reveals that I'm not alone -- lots of people have been unable to get Denon AVR's to play nice with LG TV sets via HDMI ARC connections. Do you know if it's been fixed with the eARC connection on this receiver?

I'm curious why (with the exception of their high-end model) Denon receivers don't offer 7.1 analog inputs while their sister company Marantz does. I specifically purchased a Marantz SR7011 so I could connect my Oppo UDP-205 to its 7.1 analog inputs to take advantage of the Oppo's superior DACs. I've noticed a lack of 7.1 inputs on most of the receivers recently reviewed in S&V. I can only hope Marantz doesn't follow this trend.
